Application filed Angu Tore n i n e w and useful Improvement in insulator-Knobs,

' of which the foiiowing is a specificzitiom vhereinafter fully described This invention reieies to cerinin new and useful improvements in insnioi'ing' knobs, the object being to provide a knob which is so eonstrnoted'ihat the wire to be secured can be eaeii and quickly arranged Within the knob or detached therex'roin, thereby overcoming the iiffiouities now existing in insulators in which a. straight groove is nsecL-lie i is necessary to match the grooves in order to place the Wire-therein. 1

A further object of my invent-ion is to provide an insulator which is formed of two sections normally held together, in such n manner that the iinoio can be reedii secured 0 its siipport in order to secure one Wire easily and quiekiy.

A. still further object of myiiiven'if 11 is to provide a meeting face ofthe seer-ions with circular grooves, the Walk; or" Will'ilil are provided, with tampering notches uriapler io register with one, another, and through which Wire to be secured is adapted to pass. Another objeobof my invention is to provide an insulating: knob which is exceedingly simple and cheap in construction, and one in which the securing screw extends through the two s'eefiions of the knob centrally for securing the some to 21 support, and for binding the sections together over e Wire.

, With these objects View, the invention consists in the novei feaiures of oonstrno tion, combination and arrangement of parts, and ointed out in the cieirns.
